Final boss fight plan
Prepare before the volcano trigger
Bring a late-game ranged weapon, ample ammunition, cooked healing catches, and free inventory space.
Keep a clean movement lane
Circle away from lava pools and avoid standing beneath airborne attacks or repeated stomps.
Apply controlled pressure
Fire during safe movement windows and reload only after the boss has passed or created distance.
Secure the fin
Pick up the distinct quest trophy immediately and protect it from lava, physics loss, or accidental sale.
Finish after the final boss
Return the fin to the scientist to receive the RHIB keys. Interact with the RHIB steering position to start the ending sequence.
If the wheel does not respond, a solved player report says to empty your hand before pressing the interaction key. Treat that as community troubleshooting rather than an official guaranteed fix.
